Cooperative answering of queries based on hierarchical decision attributes
Computer Assisted Methods in Engineering and Science, 2022 This paper considers decision systems (see [6]) with decision attributes which are hierarchical. Atomic queries are built only from values of decision attributes.

Mapping Object-Oriented Database Models Into RDF(S)
IEEE Access, 2018 Resource description framework RDF and RDF schema (collectively called RDF(S)) are the normative languages to describe the Web resource information. How to construct RDF(S) from the existing data sources is becoming an important research issue.

Query By Example Keyword Spotting
, 2021 Voice user interfaces have been growing in popularity and with them an interest for open vocabulary keyword spotting. In this thesis we focus on one particular approach to open vocabulary keyword spotting, query by example keyword spotting. Three types of query by example keyword spotting approaches are described and evaluated: sequence distances ...

Quantum query complexity of Boolean functions under indefinite causal order
Physical Review ResearchThe standard model of quantum circuits assumes operations are applied in a fixed sequential “causal” order. In recent years, the possibility of relaxing this constraint to obtain causally indefinite computations has received significant attention.

What's beyond query by example?
, 2003 Over the last ten years, the crucial problem of information retrieval in multimedia documents has boosted research activities in the field of visual appearance indexing and retrieval by content. In the early research years, the concept of the «query by visual example» (QBVE) has been proposed and shown to be relevant for visual information retrieval ...
